SYMPTOMS
Dead or Shutdown symptoms.
RESOLUTION
Dead symptom reported to be caused by the following:
1. Dead.
Found Q601 & Q602 shorted, R615 open, and IC600 on the A Board were the cause of the symptom.
2. Dead.
Found D614, Zener diode, on B+ line was shorted.
3. Set shutdown and the
standby LED blinks 3 then 5 times.
Found 200v line was low. Disconnected CN706 on the C Board and found 200v now
present on CN706/pin 7.
Found: IC702 (C board) shorted the 200 volt line.
HQ Comments: C541 on the A Board could become defective if
the 200v line is shorted since
the polarity on the capacitor will become reversed. R553 fuse resistor could also be opened
on the A Board.
4. Error code of 4 blinks .
Dead
set press power button you hear the relay and you see red led flash 3
times and stops? Has no HV or other action. Tech removed the back as
no 200 volt supply, did unplug CN706 and now has 200volts. Tech did
remove the IC702 and same it comes up so needs this IC.
5. Dead. 5 blinks then 3 blinks. Found shorted Damper
diode D504. Q502 has a built in damper, as well.
6. The TV does not turn On and the LED flashers 9 times.
Found one side of R610 open on the Base of Q690 on the A board.
7. Dead, 9 flashes, Q606
Would not start when cold, has stand by 5 but
relay never energize.
No response from front panel or remote controls.
9 blinks is not in service manual.
Found Q606 (Zero Det.), on the A Board, had no soldered on the collector
of the transistor causing an intermittent connection.
Soldered
the collector of Q606 and set returned to operation.
HQ Comments: Also refer to E30968554.
8. Dead. 5 blinks or 3 blinks
Found on the A Board D611 in the Power Supply open, and Hor. Output Q502 shorted.
9. Found Power Supply components D611
shorted causing Q600, Q601, and R615
to fail on the A Board.
10. No picture or sound. Standby flashes.
Found Q512 (Pin Out) shorted. on the A Board.
11. Dead. No sound or picture.
Found the FBT and Q502 were shorted, and R615 open on the A Board.
12. Dead
No power, Stand by light flashes 4 times.
Found T604 and IC601, replaced.
Found D611 on the A Board was the cause of the symptom.
13.
Dead.
Found D534 shorted on the A Board.
14. Shutdown 4 Blinks.
Replacing R595, OCP Latch Q532 on the A Board, fixed the set.
PN 1-247-891-00, 330K 1/4 watt.
15. Unit shuts down after 15 mins.
Immediate shutdown - sometimes it give a 3
blink, sometimes nothing.
Found R595 (330K) was open located in the Q532 OCP Latch circuit.
R595 P/N 124789100 330k 1/4w
16. Won't power up. LED Blinks 4 times, B+ is very low
B+ is at 49V, +15/-15 only coming up to about 1 volt.
Wth
Hor Out disconnected B+ only comes up to 50v.
Found D611 on the A Board was the cause of the symptom.
17. Intermittently does not turn on
Found a intermittent C633 on pin # 3 of IC600.
